Reference is had to the accompanying drawings which illustrate the preferred form of the invention, though it is to be 'understood that the invention is not limited to form of the holder the exact details of construction shown and described, as it is obvious that various modifications thereof Within the scope of the claims will occur to persons skilled in the art. In-said drawings:

Fig. 1 is a sectional view of the holder;

Fig. 2'is a sectional view of a modified Fig. 8 is an enlarged fragmentary sectional view through the holder, showing the joint intermediate the ends, and

Fig. 4 is a detail. sectional view of the beaded end of the inner shell of the holder.

It is the-primary object of the present invention to provide a holder for carbonated beverages, or other liquids or, gases under pressure, and one in which the danger of,

corrosion is reduced to a minimum, and

-more particularly the invention contemplates the provision of a tank.

It is a further object of the invention to provide a tank having an inner shell of substantially non-corrosive metal.

Another object of the present invention is to provide a tank having an inner shell which is formed of a suitable acid resisting metal. A still further object of this invention is the provision of a tank having a liningformed of aluminum or metal possessing the properties of aluminum. Still another object of Y the invention is the provision of a tank having an inner shell of aluminum or other substantially corrosion resistant metal and an outer shell of steel or the like shrunk thereon whereby to firmly .unite the two shells.

Another object of this invention is to provide a tank for carbonated beverages, liquids or gases under pressure having an inner'shell two shells, and to formed of united sections, and an outer shell formed of united sections shrunk onto the innershell to provide a close uniting of the effect a strong and durable structure.

Referring more particularly to the draw-- ings, the present invention comprises broadly joined together end to end atthe outwardly extending marginal flanges 3 and 4. To form a leak proof joint, the said flanges 3 and 4 are welded, soldered, or otherwise secured together throughout the entire circumference, as shown at 5 (see Fig. 3). While the drawings show the sections A and B as substantially cylindrical,.it is obvious that the sections may be shaped as desired. Referring to Fig. 1, the section 2 of the container orshell A is reduced at one end, forming a neck 6 defining an opening 7 which'is normally closed by the cap or closure D, heretoforementioned. The marginal edge of the section 2 is beaded as shown at 8, the head resting u on the marginal edge of the reduced end 9 0 section 9 of the steel outer shell B, and the opposite end of this section 9 is shown at 10.

The outer container B is formed preferably of steel or other like metal and includes, in addition to the section 9, the section 11 which has one end thereof flanged outwardly as shown at 12, and in the finished product the flanges 10 and 12 are connected together by suitable means such as rivets 13 or the like.-

An end closure C is provided'for the tank, which is, as shown, substantially convex in shape and includes a'steel main portion 14 outwardly flanged as having a lining 15 of aluminum or other like material secured thereto in any suitable manner. cylindrical hoop shape portion 16, and this closure C is so formed that a nice fit ,is 0b- The mainportion M'termin'ates in a I tained between the adjacent end of the body connected to the inner shell 1 to form a cir cumferential leak proof. joint. The closure 0' is further provided with angularly arranged integral reinforcing ribs 16, for an obvious purpose.

The cover D, shown clearly in'Fig. 1,-is preferably lined with aluminum or other corrosion resistant material as indicated at 17, and said cov'er is provided with angularly arranged reinforcing ribs 18. For retaining this cover or'end closure in engagement with the tank, bolts 19 or the like are pro vided which extend through the material of the cover and through a flange 20 formed integral-with a collar 21 which is preferably shrunk around the neck 6. The lining 17 is of such dimensions that it overlaps the beaded end of section 2 of the inner container, and

by drawing the cover into closed engagement of the tank a ring 22 is provided, which is preferably shrunk onto the tank after the same has been formed; said rings 22 being of such dimensions that when the tank is handling and in transportation.

resting horizontally as shown in the drawings, the joint intermediate the end of said tank will be protected, further such rings serve as a means for rolling the tank when desired, and also furnish a satisfactory means for preventing damage to the tank in Referring now to Fig. 2, in which is shown a modified form of tank, it can be seen that the tank disclosed in this figure is fundamentally similar to' the tank disclosed in Fig. 1, but it differs, however, inthat the tank shown in this figure is provided with only one end closure,.the opposite end being formed in-. tegral' with a section of the main body portion.

i The tank of Fig. 2 comprises an inner shell E and an outer shell F, the inner shell being formed of aluminum or other like material drawn to the desired shape, and consisting of sections 23 and 24:, the section 23being provided with a dome shaped end. -The section 24 is substantially cylindrical, and each of the sections 23 and 24 is provided with outwardly extendingflanges 25 and 26 which are welded, soldered, or otherwise secured together throughout their circumference whereby to form a leak proof joint in the manner heretofore disclosed with reference E. The open end of the tank shown in Fig.

2 is normally closedbycover30. formed of steel or the like, and said cover is preferably lined with aluminum as shown at 31. This lining 31 is of such dimensions that it overlaps the beaded end 27, which beaded end engages the extreme open end of the section 28 of the outer shell, and the cover is normally held in place by means of bolts 32 which engage the marginal flange 32 formed on a collar 34, which is preferably shrunk onto In addition to the structure herein shown and just described, a specific method of producing the tank is provided." In the manufacture of said tank I preferably form the two sections of the inner shell by drawing sheets of aluminum to the desired and required shape, to define the sections 1 and 2, and then these sections may be flanged at the proposedabutting ends. A suitable mandrel or former is then placed in the sections, separately, and a heated, preformed steel section of the required size and form is forced or otherwise placed over" each of the aluminum sections while the mandrel is in position therein. The steel sections are permitted to cool, and it will be apparent that upon cooling the steel sections Will be shrunk onto the aluminum sections with a resultant firm union and a nice fit of the aluminum and steel sections.

The mandrels may then be withdrawn andthe two united aluminum and steel sections are then placed together, end to end, and the abutting aluminum sections are united at the marginal flanges by welding. At this point in the method, the flanges 10 and 12 of the outer container are in the position illustrated in full lines in Fig; 3, and these flanges are.

then brought together as shown in dotted lines in Fig.3 and securely retained in their abutting relation by means of rivets 13. The body portion of thetank having been thus formed, I then insert the end closure C shown in Fig. 1, and weld, solder, or otherwise socure the lining 15 to the inner shell A. Following this the end closure D is applied.

Having thus described the invention, it will be apparent that a holder forcarbonated beverages, fluids or gases under pressure has been provided which, due to its specific form, is greatly resistant to acid or other corrosion and said holder is strong and durable due to the fact that the outer container or shell has been shrunk onto the inner container or shell.
